Where is the "Harold's Circle"

Somebody might have already asked this but...
I finished all of the "Former Chapions" in the Boston Brawlers club set and it says now I have to face the current ones.
It says I need to "Go to the Harold's Circle at the Brewery" I have looked in Boston, New York, (which has a brewery fast travel station), and I have even looked in the Fronteir. There isn't an icon on any of the maps and I have run around all over the place. Can anyone help me find the circle?
I am lost and have no clue where to start looking again.

.... Yeah there is no map icon and I know its near a brewery but which one and where exactly I can't remember. I do remember finding my help in the trophy guide disscusion thread and the guide itself. Look there if you can't get exact directions form someone...\
